Anyone experienced problems with running Ajax T/C from a controller? I get very high CPU on the load generator (tried different machines). Also sometimes it fails to exit safely and hangs in 'Exiting' mode.

Are you able to run the TruClient vusers on another machine? Also, how many vusers are you running and what version of LR?

Depending on the hardware and actual overhead of the script itself IE number of calls being asynched you might see that. Our current average is about 9 virtual users running some of our pages on Quad Xeon 2.3 ghz, 4Gig ram machines.. It's come a long way, but calibration of vuser/machine is definitely needed with this protocol before doing a full blown load test. Don't expect 100+ vusers on normal machine setups that is for sure.

I tried it on different machines, different versions, including latest one. Reproduced with 5 & 50 users
